Scorezilla MCP Tools (9)
list_games
Lists your games. Use this first to orient.
list_boards
Lists leaderboards under a game.
get_keys
Returns the public key (safe to embed) and the secret-key prefix. The full secret never leaves the dashboard.
get_board_top_n
Returns the top entries on a board. The "is my integration working?" tool.
get_sdk_snippet
Returns ready-to-paste integration code for a board. Optional axis args tailor it: anonymous/OAuth identity, client-only vs. server-validated **anti-cheat**, and the server language (TS/Python/Go/C#).
bootstrap_leaderboard
Creates a new game + first board in one call, then returns the **widget embed** + **SDK snippet** + a plain-English recommendation. Same optional axis args (anti-cheat, OAuth, server language). The 90-second-demo path.
create_game
Creates a new (empty) game. Use when a game already exists (so `bootstrap_leaderboard` would conflict) or you want another.
create_board
Adds a leaderboard board to an **existing** game (by `gameId`), with full options (sortDir, scoreKind, retention, bounds).
mint_key
Mints a fresh public/secret key pair for an existing game. The secret is shown once.
